curely stayed down at its ends without restricting expansion andcontraction of metal, and additional support or bracing given to thedraft sills or draft portions of the center sills, and parts carriedthereby, these latter results being accomplished without detract-- ingfrom the desirable qualities of a head block construction.

Such im rovements are hereinafter described an shown in the accompanyingdrawings in which like reference characters refer to like parts, and inwhich Figure 1 is a side elevation with parts broken away and parts insection of the end of a tank ear, the trucks being removed; Fig. 2 is anend elevation of the same; Fig. 3 is a plan view of the same, the tankbeing removed; Fig. 4 is a sectional end elevation of the structureshown in Fig. 1 on the line 44 of Fig. 3; Fig. 5 is a detail sectionalpers ective view of one of the head block end races showing alsoportions of the up er and lower head block tie members, and ig. 6 is amodification of the same.

Referring now in detail to the drawings, 1 represents the side sills, 2the center sills, and 3 the end sills of'the underfr ame of the car.

4 are the cross-bearers connecting the side sills 1 and the center sills2.

5 are saddle members mounted on crossbparers 4 and adapted to supportthe, tank 6.

"lank 6 may be su'itably stayed down upon saddles 5 by turn-bucklestraps 7 suitably secured to the car underframe.

At each end of the car is an end sill cover plate- 8 riveted to theupper flanges of the side and end sills and further-riveted at anintermediate portion to the central head block brace 9 which is rivetedto the center sills 2'and which extends upwardly through a notch 10 in.said end sill cover plate; 11 is the head block which rests at itscentral portion upon the center sill structure of the car and which issup orted near its outer ends by the lower hea block tie members 12secured at their forward ends to brackets 13 riveted to the end sills 3.Lower tle members 12 are preferably of pressed steel formation, theirflanges de ending and embracing at their outer ends t e sides of thebrackets 13. Tie members 12 are'fiattened and se cured by rivetingthrough the lower outer flanges of the saddle members 5, the cover plateof the cross-bearers 4 and the upper he outer flanges of thecross-bearers 4. ends of the head block's therefore rest upon the websof the lower tie members 12 14 are angular braces, one near each end ofthe head blocks 11, having a horizontal outward portion riveted to theend sill coyer plate 8, a U-shaped intermediate portion riyeted to thewebs of the .lower tie members 12 and a vertical inner portion abuttingand bolted to the head blockl 1. 1'4 brace the head block 11, stiffenthe lower tie members 12 and help to supportend sill cover plate 8.

15 are upper tie members, one neareach end of head blocks 11, bent overthe head block 11 at their forward ends and extending from the forwardedge of the head block 11 over the upper surface of said head blockdownwardly to and riveted to the outer lower flanges of the saddlemembers 5, the

cover plate of the cross-bearers 4 and to the upper outer flanges ofsaid cross-bearers 4.

Angular braces Lower tie members 12 and upper tie members 15 are furthersecured in position and to said head block 11 by vertical bolts whichpass through the head block and through said members, there beingfurther a washer plate 16 carried by the bolts at their lower ends.

17 are head block end braces, one near each end of the head block,interposed betweenthe lower tie member 12 and the upper tie member 15,here shown polygonal m shape and formed of castings having a centralverticalweb with peri heral flanges extending in either direction terefrom. Braces 17 are secured to lower tie members 12 and through saidmembers and through the upper tie members 15 by rivets which pass,

flanges of the braces 17. Braces 17 are furthermore seqired to the headblock by means of horizontal bolts which pass through (the flanges ofthe braces and through the area, thus obtaining about an equal strengthhead block, which bolts carry washers at their outer ends bearingagainst-the outer face of the head block; braces 17, therefore, furtherserve to secure tie members 12 and 15 to head block 11. Braces 17-may bemade of pressed steelt'if desired, as shown in Fig. 6.-

The tie m mbers12 and-15 are so bent that I they meet at a point betweenthe cross-bearers and the head block endbraces at which point they aresecured by means of rivets. this way the stress is transformed into ashearing stress in the rivets. A further ob ject of connecting the tiemembers 12 and 15 at this point is to obtain an increased rivet betweenthe rivets and the smallest transverse sectional area of the top tiemember to resist the turning action of the head block.

18 are end stay straps, one at each extreme end of tank, looped over theupper surface of the tank andconnected to turnbuckles 19 which aresuitably connected by link 20 to a ribbed anchor yoke 21; anch'or yoke21 extends beneath the draft portions of the center sills 2and forms asu port for the draft portions of the center s' ls 2, the

draft-gear and other parts carried by the draft portions of the c entersills 2 likewise forming a brace for the draw ,bar guide or carrier late22, and the anchor yoke 21 is bolted t rough its web portions to thedraw bar guide or carrier plate 22 and the lower flanges of the centersills. u

The form of head block end braces-herein shown and described not onlypermits of the .location of the end tank stays nearer or at the extremeends of the tank, butth-ey fur thermore permit of the bringin of saidstays directly down to the center s' s where they are secured, to theiranchor yokes. With this construction it will be seen that the endinvention.
